Question

which semantic element is best suitable for content like blog post that is self contained, independent and can be republished?

Answer 1

The answer is <article>.

The semantic element that is best suitable for content like blog post that is self contained, independent and can be republished is <article>. The content enclosed in the article tag must make sense by itself and independent of the remaining content in the website. Other instances where the article tag is used are newspaper articles and forum posts. An <article> tag must end with an </article> tag.
